Definitions

  • the present invention relates to a medicine dispensing apparatus that includes a large number of medicine feeders configured to contain medicines such as tablets, which may be individually discharged and consecutively discharge the medicines, as classified by type, and that automatically discharges and dispenses desired medicines according to a prescription or a medicine dispensation instruction.
  • a medicine dispensing apparatus including a temporary reserving structure between a medicine guide structure and a medicine collecting structure.
  • Some medicine dispensing apparatuses affix a wireless tag to packs immediately after the completion of packing while packing medicines one after another (see Patent Document 2, for example).
  • false packing is clarified by writing information reflecting such a difference in a wireless tag and affixing the wireless tag over a printed region of a package band.
  • many medicine dispensing apparatuses include: a housing; a plurality of medicine feeders configured to contain medicines and consecutively discharge the medicines, and a plurality of medicine feeder storage portions each configured to store the plurality of medicine feeders; a medicine guide structure disposed between a pair of adjacent medicine feeder storage units to guide the medicines discharged from the plurality of medicine feeders included in the pair of medicine feeder storage units to a single outlet port located at a lower part of the medicine guide structure; and a medicine feeder storage portion configured to store the pair of medicine feeder storage units and the medicine guide structure.
  • one or more medicines of one or more types are discharged from medicine feeders containing such medicines according to a medicine dispensation instruction, the discharged medicine or medicines are led downward by the medicine guide structure at applicable locations, and thereafter a plurality of medicines having fallen from the medicine guide structure are collected by a medicine collecting structure and put into a packing device located under the medicine collecting structure so that the prescribed medicines are consecutively packed according to the types of medicines.
  • Medicine dispensing apparatuses including a temporary reserving mechanism between a medicine guide structure and a medicine collecting structure are also practically used (see Patent Documents 3 and 10, for example).
  • While some temporary reserving mechanisms are of a dependent type that are mounted in a medicine feeder storage portion and are drawable together with medicine feeders and a medicine guide structure (see Patent Document 3, for example), other temporary reserving mechanisms are of an independent type that are mounted under a medicine feeder storage portion and are not necessarily drawn together with medicine feeders and a medicine guide structure.
  • the operation characteristics can be addressed by providing the temporary reserving structure, which can isolate the effect of the fluctuations in the falling time of discharged medicines in the medicine guide structure from the medicine collecting structure and hence the packing device located below.
  • the number of rows of the medicine feeders in the medicine feeder storage portion can be increased without adversely affecting the performance of the packing device.
  • the temporary reserving structure is pre-mounted only in a medicine feeder storage portion in which medicine feeders of a cassette mount-unmount type exclusively for specific tablets, as will be discussed later, are mounted in a large number of rows.
  • the temporary reserving structure is yet to be mounted in a medicine feeder storage portion in which medicine feeder of a non-cassette type adaptable to many types of medicines, also as will be discussed later, are mounted in a small number of rows.
  • the large number of medicine feeders (tablet feeders) mounted in the medicine dispensing apparatuses each include a container portion configured to contain and hold usually a large number of medicines (tablets) of a single type collectively input and cause the medicines to consecutively fall when driven for discharge, and a base portion (driving portion) configured to support the container portion and drive the container portion for discharge.
  • medicine feeders adaptable to many types of medicines are to be mounted in a medicine dispensing apparatus in which a large number of medicine feeders are mounted, it is in only a few cases that medicine feeders adaptable to many types of medicines are used for all or most of the medicine feeders. In many cases, however, medicine feeders adaptable to many types of medicines are used for a small number of the medicine feeders, and medicine feeders exclusively for specific medicines are used for most of the medicine feeders.
  • the two types of medicine feeders can be advantageously selectively used as discussed above, since there is a clear difference between the two types.
  • medicines are clearly separated in the front-rear direction by mechanical means such as a partition member when medicines to be discharged are aligned, and contained in sectioned chambers, one medicine in each chamber (see the device according to Patent Document 8, which is permanently exclusively for specific medicines, and the device according to Patent Document 9, which is exclusively for specific medicines in an assembled state).
  • the medicine feeders exclusively for specific medicines can also be called "medicine feeders of a medicine row front-rear splitting type".
  • the medicine feeders of a non-cassette, fixed type adaptable to many types of medicines include a member configured to regulate the lateral width of a medicine transfer path, but do not include a member as mechanical means for clearly separating a medicine to be discharged and the following medicine waiting to be discharged, or sectioned chambers.
  • the medicine feeders adaptable to many types of medicines can also be called "medicine feeders of a medicine row front-rear non-splitting type". As discussed earlier, the medicine feeders of this type are yet to be combined with a temporary reserving structure.
  • an object of the present invention is to improve a medicine dispensing apparatus so as to give a sufficient sense of security even if medicine feeders adaptable to many types of medicines are mounted.
  • the individual medicine feeders do not operate very frequently, since only medicine feeders containing medicines to be dispensed need to operate while medicine feeders containing medicines other than those to be dispensed do not need to operate.
  • the temporary reserving structure operates frequently, since the temporary reserving structure operates every time packing is performed as with the packing device, irrespective of the types of the medicines. As a result, maintenance such as check and repair of the electric motor also needs to be performed frequently if the electric motor operates frequently.
  • a portion of the packing device which includes a plurality of electric motors generally occupies the lower portion of the housing, and is structured to allow the electric motors to be exposed by drawing the device forward out of the housing together with a support substrate.
  • the electric motors of the packing device can be maintained in both the front side and a lateral side and thus with a light work burden.
  • the drive system of the temporary reserving structure including a power transmission member and an electric motor, is disposed deep inside the housing, since higher priority is given to cleaning medicine dust etc., which is frequently performed by the user by drawing the medicine guide structure and the medicine collecting structure forward out of the housing.
  • the electric motor and the power transmission member remain deep inside the housing even in medicine dispensing apparatuses in which an open-close member etc. as a main component of the temporary reserving structure can be drawn forward out of the housing (see Patent Document 3, for example). Therefore, maintaining the electric motor of the temporary reserving structure is basically performed in the rear side or a rear lateral side of the housing.
  • Another object of the present invention is to improve a medicine dispensing apparatus such that maintenance for an electric motor of a temporary reserving structure is facilitated.
  • a medicine dispensing apparatus includes: a housing 10A; a plurality of medicine feeders 13, 86 configured to contain medicines and consecutively discharge the medicines, and a plurality of medicine feeder storage units 131, 132, 133 each configured to store the plurality of medicine feeders 13, 86; a plurality of medicine guide structures 20, 90 provided in correspondence with the medicine feeder storage units 131, 132, 133 to guide the medicines discharged from the plurality of medicine feeders 13, 80 included in the corresponding medicine feeder storage unit 131, 132, 133 to a single outlet port located at a lower part of the corresponding medicine guide structure 20, 90; a plurality of medicine feeder storage portions 12A to 12C each configured to store the corresponding medicine feeder storage unit 131, 132, 133 and the corresponding medicine guide structure 20, 90; a medicine collecting structure 30 disposed in the housing 10A under the plurality of medicine guide structures 20, 90 to collect the medicines having fallen from the plurality of medicine guide structures 20, 90; a packing device 40 provided in the housing under the medicine collecting structure 30 to
  • the medicine feeder storage unit 133 included in one 12C of the plurality of medicine feeder storage portions 12A to 12C includes a plurality of medicine feeder mount portions 80 in which a plurality of general-purpose medicine feeders are mounted on a plurality of drawer shelfs 82 provided vertically and configured to be individually drawable, the plurality of general-purpose medicine feeders each including a container portion and a successive discharge mechanism portion that are integrated with each other.
  • One 90 of the plurality of medicine guide structures 20, 90 that is provided in correspondence with the medicine feeder storage unit 133 including the plurality of medicine feeder mount portions 80 is allowed to be drawn out of the housing 10A when all of the plurality of medicine feeder mount portions 80 are drawn out.
  • a temporary reserving structure 97 is provided at a lower end portion of the one 90 of the plurality of medicine guide structures 20, 90 that is provided in correspondence with the medicine feeder storage unit 133 including the plurality of medicine feeder mount portions 80, the temporary reserving structure 97 being operable to temporarily reserve the medicines fallen from the medicine guide structure 90 and cause the medicines to collectively fall down into the medicine collecting structure 30.
  • the control portion is configured to also control operation of the temporary reserving structure. When it is detected that an excessive medicine has been discharged from the medicine feeder 86 included in the medicine feeder storage unit 133 including the plurality of medicine feeder mount portions 80 during packing operation, the control portion temporarily stops the packing operation and causes the temporary reserving structure 97 to reserve the medicines.
  • control portion allows an operation to draw out the plurality of medicine feeder mount portions 80 included in the applicable medicine feeder storage unit 133, and thereafter allows resuming the packing operation when it is detected that the plurality of medicine feeder mount portions 80 are drawn out of the housing 10A and pushed back.
  • the medicine feeder storage portion 12C in which the general-purpose medicine feeders 86 are to be mounted is divided into a plurality of medicine feeder mount portions 80 configured to be individually drawable, and the general-purpose medicine feeders 86 are mounted in a distributed manner in the medicine feeder mount portions 80.
  • the temporary reserving structure 97 is provided at the lower end portion of the medicine guide structure 90 shared by the plurality of medicine feeder mount portions 80, and an excessively discharged medicine is reserved in the temporary reserving structure by the control portion not only temporarily stopping the packing operation but also causing the temporary reserving structure 97 to reserve the medicines when discharge of an excessive medicine is detected.
  • the control portion further performs control so as to enable and facilitate the work of manually removing the excessively discharged medicine from the general-purpose medicine feeders.
  • control portion allows an operation to draw out the medicine feeder mount portions 80 of the applicable medicine feeder storage portion 12C.
  • the applicable medicine feeder mount portions 80 are manually drawn out of the housing to make it possible to draw out the medicine guide structure 90
  • the medicine guide structure 90 is also manually drawn out of the housing 10A
  • the excessively discharged medicines are manually selected and taken out of the temporary reserving structure 97 which has been drawn out accordingly, and then the parts which have been drawn out are pushed back into the housing 10A in the reverse order.
  • it is automatically detected that the applicable medicine feeder storage portion 12C is drawn out of the housing and pushed back, which accordingly enables automatic packing operation to be resumed.
  • a user can be given a sufficient sense of security even if the general-purpose medicine feeders 86 of a fixed container portion type which have been developed later are mounted in addition to the medicine feeders 13 of a cassette mount-unmount type which have been developed earlier and have been familiar.
  • the medicine dispensing apparatus may further include a display member configured to indicate the medicine feeder 86 that has discharged an excessive medicine when such excessive discharge is detected.
  • a display member configured to indicate the medicine feeder 86 that has discharged an excessive medicine when such excessive discharge is detected.
  • control portion CR causes the medicine feeders 86 included in the medicine feeder storage unit 133 including the plurality of medicine feeder mount portions 80 to perform medicine discharge operation and causes the packing device to perform the packing operation without waiting for an instruction for the packing operation when operating power is turned on and during other initial operation.
  • undesired remaining medicines are automatically discharged and packed and thus can be disposed of reliably and collectively without being overlooked, even if there are remaining medicines that cannot be grasped during initial operation due to past operation, manipulation, etc. that are not automatically detectable.
  • a plurality of temporary reserving structures 60 each including a reserving portion 65 are also provided under the plurality of medicine feeder storage units 131, 132 included in the plurality of medicine feeder storage portions 12A and 12B other than the one 12C of the plurality of medicine feeder storage portions 12A to 12C.
  • the plurality of temporary reserving structures 60 are each operable to temporarily reserve, in the reserving portions 65, the medicines fallen from a corresponding one of the plurality of medicine guide structures 20 and cause the medicines to collectively fall down into the medicine collecting structure 30.
  • the medicine dispensing apparatus further includes a drive mechanism operable to drive the plurality of temporary reserving structures (60, 97).
  • a front-side portion 22 of a lower end portion of an inner wall portion of at least one 20 of the plurality of medicine guide structures 20 is located in rear of a front-side portion 21 of an upper end portion of the inner wall portion of the at least one medicine guide structure 20; a front end of the reserving portion 65 of the temporary reserving structure 60 is located in rear of a front surface of the housing; and an electric motor 51 operable to provide a closing drive force or an opening drive force to the drive mechanism is located in front of the reserving portion 65.
  • the plurality of medicine feeder storage portions 12A and 12B may be arranged side by side in the housing 10A.
  • a transmission shaft 64a may be provided to extend in a front-rear direction along the reserving portion 65 of the temporary reserving structure 60 provided for the medicine guide structure 20 in any one 12A of the plurality of medicine feeder storage portions 12A and 12B.
  • a transmission mechanism 70 operable to transmit motion of the transmission shaft 64a to a plurality of open-close mechanisms provided for the plurality of medicine feeder storage portions 12A to 12C may be provided in rear of the reserving portion inside the housing 10
  • the electric motor may drive the transmission shaft. With such a configuration, drive of the electric motor is transmitted rearward via the transmission shaft, even if the installation location of the electric motor is changed from the rear to the front.
  • the transmission mechanism for allowing the plurality of temporary reserving structures to share the drive of the electric motor is allowed to remain deep inside the housing as in the related art, advantageously reducing the burden of modification such as change in structure or members.
  • the electric motor 51 is located in front of the reserving portion 65 of the temporary reserving structure 60 in one 12A of the plurality of medicine feeder storage portions 12A to 12C that is located closest to a side in the housing.
  • the electric motor is provided in front of a temporary reserving structure that is located closest to a side when a plurality of temporary reserving structures are provided.
  • maintenance for the electric motor of the temporary reserving structure can be clearly performed in a front-side lateral location in addition to the front side, further enhancing the degree of freedom in the maintenance.
  • the transmission shaft 64a serves as a support shaft for the open-close mechanism of the temporary reserving structure.
  • the support shaft for the temporary reserving structure also serves as a transmission shaft, it is not necessary to add a transmission shaft, avoiding an increase in the number of members which tends to incur an increase in the burden of cost and design.
  • a cam mechanism operable to convert motion for one rotation of an output shaft of the electric motor 51 into reciprocal rotational motion of the transmission shaft 64a may be provided between the electric motor 51 and the transmission shaft 64a, and the transmission mechanism 70 may be composed of a link mechanism.
  • the link mechanism of the transmission mechanism 70 drives the open-close mechanism of the temporary reserving structure 97 provided at the lower end portion of the medicine guide structure 90 provided in correspondence with the medicine feeder storage unit 133 including the plurality of medicine feeder mount portions 80.
